A case of Anderson-Fabry disease: a multidisciplinary approach for diagnosis and follow up

Abstract

Fabry disease (also known as Anderson-Fabry disease, angiocheratoma corporis diffusum, diffuse angiocheratoma) is a rare tesaurismosis linked to the deficiency of the lysosomal enzyme alpha-galactosidase A, required for the physiological catabolism of glycosphingolipids.

The related clinical signs show a multisystemic feature and define a degenerative and disabling pathology, whose approach requires a close multidisciplinary specialist collaboration.

Currently, the renewed interest in the disease is aimed at the need to provide an early diagnosis, in order to early begin the enzyme replacement therapy and to slow down or avoid the establishment of irreparable organ damage. For this reason, the diagnostic suspicion becomes crucial and arises from the careful observation and research of the symptoms, together with the anamnesis and the overall clinical evaluation of the patient.

CASO CLINICO

Riportiamo il caso di un paziente di 47 anni, portatore di fattori di rischio per vasculopatia (BMI >35, dislipidemia, fumo, ipertensione arteriosa) e in follow up per insufficienza renale cronica stadio IIIa secondo NKF/KDOQI (sCr 1,3 mg/dL con eGFR 65 mL/min/1,73 mq sec. MDRD), ACR grado A2 (150 mg/g) confermate in più determinazioni successive nell’arco di sei mesi. L’ecografia renale non rivelava alterazioni degne di nota. In precedenza, non era stato possibile effettuare una diagnosi istologica avendo il paziente rifiutato di sottoporsi a biopsia renale.
